IFE is not provide on any BA shorthaul routes from LGW or LHR regardless of aircraft used.
Exceptions are the longer "band 4" flights eg LCA. DME, ATH, tripoli, istanbul etc etc.
The aircraft may have the screens, but it wouln't be in use.
Not sure that many airlines on short sectors provide IFE with the exception of a moving map display, which you will find on most BA airbuses.
